In this tutorial, we’ll explore Java’sInterruptedException. First, we’ll quickly go through the life cycle of a thread with an illustration. Next, we’ll see how working in multithreaded applications can potentially cause anInterruptedException. Finally, we will see how to handle this exception...

} catch (InterruptedException e) { e.printStackTrace(); } } } }).start(); } } 在这个例子中,当用户启动应用时,onCreate方法会初始化界面并启动一个后台线程,该线程每隔2秒发送一条消息给主线程的Handler,Handler接收到消息后,根据消息的内容(what字段)切换图片资源。
Thread.interrupt() 用于将当前线程的中断标志位设置为true,如果是wait、sleep、join造成的阻塞,会重新将标志位设置为false,抛出interruptedException异常。如果是IO阻塞会抛出异常,如果是轮询,直接返回。如果是非阻塞的线程,进入阻塞会按照阻塞来处理,非阻塞中断标志位为true的线程遇到wait、join、sleep,直接抛出interruptExce...
